DOOR-OPERATING MECHANISM.

Specification of Letters Patent.

Patented June 16, 1914.

To all whom it may concern Be it known that 1, Louis A. Kn1NG, a citizen of the United States, residin 1n East Cleveland, county of Ouyahoga, tate of Ohio, have invented certain Improvements in Door-Operating Mechanism, of which the followin is a specification.

My invention reTates to certain improvements in mechanism for opening and closlng doors and especially the doors at the side of a passenger car, whereby either one or both of the doors can be opened or closed, as desired, by a conductor or a motorman. In certain types of cars the conductor controls the doors and in other types of cars the motorman controls the doors. It will be understood, however, that the invention can be used for operating doors other than those of passenger cars.

The object of the present inventlon is to simplify the construction of the mechanlsm and to locate the major portion below the surface of the floor. The operating levers are located on the platform some distance from the doors sothat either one of the doors can be opened or closed or both doors can be opened or closed simultaneously by the operator without leaving his station.

In the accompanying drawings: Figure 1 is a skeleton side view of sufficient of a passenger car to illustrate my invention, showing the lever mechanism in full lines; Fig. 2 is a plan view; and Fig. 3 is a detached longitudinal sectional view showing the operatingshafts.

Referring to the drawings, 1 is the floor of the platform of a car, in the present instance.

2 is the entrance door and 3 is the exit door. These doors are adapted to slide in suitable ways and to close the entrance and exit passages leading respectively to and from the car. When the doors are in the central position, both passageways are open, but when the doors are in the position illustrated in the drawings, then both passageways are closed. The doors, in the present instance, are actuated by a conductor located at a station about the center of the platform.

Mounted under the platform is a transverse shaft 4. This shaft is hollow and extending through the shaft is a second operating shaft 5. The operating shaft 4 is adapted to a bearing 6 secured to the under side of the platform and to a bearing 7 mounted in one of the beams of the platform. On the inner end of the hollow shaft 4 is an arm 8, which is connected to an operating lever 9 by a link 10. This operating lever is pivoted at 11 to a stand mounted on the floor of the platform and has at its upper end a laterally extended hand grip 12. Secured to the opposite end of the hollow shaft 4 is a long lever 13, which is slotted longitudinally at its upper end at 14 and has an angular portion 15. Projecting into the slot is a pin 16 on the door 2 so that as the lever 9 is moved in the direction of the arrow, Fig. 1, the lever 13 will be moved in the direction of its arrow. moving the door into the open position. The pin, as the lever 13 swings, travels in the slot 14. When the door is in the extreme closed position, as illustrated in Fig. 1, then the pin 16 rests in the angular portion 15 of the slot and thus locks the door so that it cannot be opened except by actuating the lever 9. On the inner end of the inner shaft 5 is an arm 17 connected by a rod 18 to a lever 19 which is pivoted at 11 and extends parallel with the lever 9, having at its outer end a lateral hand hold 20. The two hand holds 12 and 20 are preferably arranged on the same line and the levers are so close together that the operator can grasp either hand hold, or, if desired, both hand holds can be grasped simultaneously so that in the first instance either one of the-levers will be actuated and in the second instance both of the levers will be actuated simultaneously.

Secured to the outer end of the shaft 5 is a lever 21 having a slot 22 which has an angular portion 23 at its upper end and adapted to this slot is a pin 24 on the door 3 so that when the lever 19 is moved in the direction of the arrow, Fig. 1, the exit door 3 will be opened; the pin 24 traveling in the slot 22 and when the door is closed the pin is in the angular portion of the slot, as illustrated in Fig. 1, and the door is locked in the closed position.

By the above construction, it will be seen that I provide a simple .and effective mechanism for operating sliding doors, particularly the doors of passenger cars, and that either one of the doors can be opened or closed, or both doors can be operated simultaneously.

It will be understood that the levers for actuating the doors can be placed at any convenient point on the platform, or, in fact, within the body of the car, if found desirable. The position of the operating levers 9 and 19 can be varied by merely lengthening or shortening the connecting rods 10 and 18.

I claim:

The combination in sliding door actuating mechanism, of a floor; two doors arranged to slide from and toward each other above the floor; two shafts located one within the other below the floor; an arm connected to each shaft, one arm engaging one door and the other arm engaging the other door; and

name to this specification, in the presence of two subscribing Witnesses.
